Objective To compare the effects of Jianpi Shengxue Granule and Hexue Capsule in treating patients with iron deficiency anemia. Methods All 120 patients with iron deficiency anemia were randomly recruited into group A (treated with Jianpi Shengxue Granule) and group B (treated with Hexue Capsule), with 60 patients in each group. The levels of serum iron (Fe), total iron binding capacity (T IBC), transferrin saturation (TS), transferrin (Tf), ferritin (SF), hemoglobin (Hb) and serum soluble transferrin receptor(sTIR) were observed in both groups. Results Jianpi Shengxue Granule showed better results in treating patients with iron deficiency anemia than Hexue Capsule with significant difference (P<0.05). Conclusion Jianpi Shengxue Granule is effective in treating iron deficiency anemia.

Objective Review the epidemiology, injuries and assessments for body impairment on the injured children and teenagers in road traffic accidents (RTAs). Methods The data of 256 cases of assessment for body impairment of the injured children and teenagers in RATs was studied retro spectively. Results Boys were injured more than girls, mainly 6-18 years of age. RATs occurred mostly in 10-12a.m and 4-6p.m. The types of vehicles were mostly car and wagon. The commonest accidents were injury of pedestrians. The sites of injures were mainly head and extremities, the commonest injures were fracture, contusion and wound, the degree of internal organ injuries was relatively slight, the fracture of lower extremities was far more often than the upper extremities. Most of the injuries were assessed to be of medial injury. In most of the cases the rate of disability was evaluated to be lighe (33.2%), in which Ⅸ , Ⅹ grade were the commonest. Conclusion The criterion of assessment for body impairment of the injured in RTAs should be broadened properly, some special items for children and teenagers should be added.

The relationship between apoptosis of granulosa cells and follicle development arrest in polycystic ovarian syndrome (PCOS) rats, and the contribution of tumor necrosis factor related apoptosis inducing ligand (TRAIL) in apoptosis of granulosa cells were explored. By using sodium prasterone sulfate rat PCOS model was induced. The apoptosis of granulosa cells in ovaries of rats was observed by TdT-mediated dUTP-biotin nick end-labeling (TUNEL), and the expression of TRAIL protein and mRNA in granulosa cells was detected by using immunohistochemical staining and reverse transcription polymerase chain reaction (RT-PCR) respectively. The apoptotic rate and the expression of protein TRAIL in granulosa cells were significantly higher in antral follicles from the PCOS rats than in those from the control rats (P<0.01, P<0.05). There was no significant difference in apoptotic rate and the expression of TRAIL protein in granulosa cells of preantral follicles between the PCOS rats and the control rats (P>0.05). No apoptosis and the expression of TRAIL protein in granulosa cells of primordial follicles were found in the two groups. The expression of TRAIL mRNA was significantly stronger in granulosa cells from the PCOS rats than in those from the control rats (P<0.01). It was suggested that the apoptotic rate in granulosa cells was significantly higher in antral follicle from the PCOS rats than in those from the control rats. TRAIL played a role in regulating the apoptosis of granulosa cells in PCOS rats.

Objective To evaluate the effect and safety of the intermittent deferoxamine therapy on relieving iron overload caused by transfusion in senile. Method Twenty-three senile with iron overload caused by transfusion were administered in a total daily dose of 20 - 50 mg/ ( kg·d ) for 5 - 6 days per week every 4 -6 weeks,the maximal dose was 2000 mg/d, add in 0.9％ sodium chloride 500 ml, continuous intravenous drip for 6 h. Result Nine months after therapy, serum ferritin fell from (2771.5±735.3)μg/L to (2483.7 ±724.4) μg/L (P＜0.01), and urine ferritin elevated from (9.68 ±5.39)μg/L to (12.14±5.50) μ g/L (P＜0.01 ). Conclusion It shows that intermittent deferoxamine therapy can reduce the serum ferritin with no significant toxicity.

Objective To investigate the effects of reactive oxygen species (ROS) inhibition on the down-regulation of adiponectin (ADPN) in mouse 3T3-L1 adipocytes by advanced glycation end-products (AGEs).Methods AGEs were prepared for incubating with cell.3T3-L1 preadipocytes were cultured in vitro and differentiated into mature adipocytes.Cell differentiation and lipid accumulation were determined by oil red O staining.After being intervened with AGEs,2',7'-dichlorofluorescein diacetate (DCFH-DA) was used as a reactive oxygen species (ROS) capture agent and the fluorescent intensity of 2',7 '-dichlorofluorescein (DCF) was detected by flow cytometry.Adiponectin expression under AGEs in 3T3-L1 adipocytes pretreated with N-acetyl-L-cysteine(NAC) or not was detected by real-time fluorescent PCR and ELISA.Results The level of ROS in 3T3-L1 adipocytes treated with AGEs was increased.mRNA and protein of ADPN were down-regulated.After inhibition with ROS,mRNA and protein expressions of ADPN injured by AGEs were ameliorated.Conclusion Exposure of 3T3-L1 adipocytes to AGEs induces oxidative stress in vitro,which decreases the expression of ADPN,and causes functional impairment of adipose cells and insulin resistance.

Objective To investigate the effect of electro-acupunctare at zusanli on acute lung injury in a rat model of sepsis after scald.Methods Fifty SPF male Sprague-Dawley rats,weighing 200-250 g,aged 2-3 months,were randomly divided into 5 groups (n =10 each) using a random number table:control group (group C),sepsis after scald group (group SS),electro-acupuncture at zusanli group (group E),electric stimulation of non-acupoint group (group NE) and electro-acupuncture at zusanli + α-bungarotoxin (α-BGT,a selective α7 nicotinic acetylcholine receptor antagonist) group (group α-BGT).The rats were subjected to a third degree scald covering 20％ total body surface (TBS) and muramyl dipeptide (MDP) 5 mg/kg was injected into the femoral vein immediately after scald to induce sepsis.Electro-stimulation (3 V,2 ms,3 Hz) of bilateral zusanli was performed for 12 min starting from the time point immediately after MDP injection and every 8 h for 2 consecutive days in group E.In group NE,electro-stimulation was performed at the points 5 mm lateral to the bilateral acupoints of Zusanli and the method was similar to those previously described in group E.In group α-BGT,α-BGT 1.0 μg/kg (in 1 ml of normal saline) was injected into the femoral vein before electro-stimulation of zusanli.At 48 h after treatment,arterial blood samples were obtained for determination of serum tumor necrosis factor-alpha (TNF-α) and high mobility group box-1 (HMGB1) protein levels (by ELISA) and lung specimens were removed for microscopic examination and for determination of the expression of Nod like receptor 2 (NLR2) mRNA (by RT-PCR) and receptor interacting protein 2 (RIP2) in the lung tissues (by Western blot).Results Compared with group C,the expression of NLR2 mRNA and RIP2 was significantly up-regulated,and the serum TNF-α and HMGB1 levels were increased in SS,NE and α-BGT groups (P ＜ 0.05),and no significant change was found in the parameters mentioned above in group E (P ＞ 0.05).Compared with group SS,the expression of NLR2 mRNA and RIP2 was down-regulated,and the serum TNF-α and HMGB1 levels were decreased in group E (P ＜ 0.05),and no significant change was found in the parameters mentioned above in NE and α-BGT groups (P ＞ 0.05).Compared with group E,the expression of NLR2 mRNA and RIP2 was significantly up-regulated,and the serum TNF-α and HMGB1 levels were increased in NE and α-BGT groups (P ＜ 0.05).The pathological changes of lung tissues were significantly reduced in group E as compared with group SS.Conclusion Electro-acupunctare at Zusanli can reduce acute lung injury in a rat model of sepsis after scald and inhibition of NLR2/RIP2 signaling pathway and activation of cholinergic anti-inflammatory pathway in lung tissues may be involved in the mechanism.
